Calibrachoa plant named &#39;duecalhulgo&#39;

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Duecahulgo’, characterized by its compact, semi-upright and outwardly spreading to trailing and decumbent plant habit; freely branching habit; early and freely flowering habit; large orange-colored flowers with brownish red-colored centers and venation; and good garden performance.

BOTANICAL DESIGNATION

Calibrachoa sp.

CULTIVAR DENOMINATION

‘DUECAHULGO’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant, botanically known as Calibrachoa sp. and hereinafterreferred to by the name ‘Duecahulgo’.

The new Calibrachoa plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new compact Calibrachoa plants with largeand uniquely attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made bythe Inventor in June, 2012 in Rheinberg, Germany of a proprietaryselection of Calibrachoa sp. identified as code number A11-2664-002, notpatented, as the female, or seed, parent with a proprietary selection ofCalibrachoa sp. identified as code number A10-3125-003, not patented, asthe male, or pollen, parent. The new Calibrachoa plant was discoveredand selected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in Rheinberg, Germany in May, 2014.

Asexual reproduction of the new Calibrachoa plant by vegetative terminalcuttings in a controlled greenhouse environment in Rheinberg, Germanysince June, 2014 has shown that the unique features of this newCalibrachoa plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duecahulgo’. These characteristics incombination distinguish ‘Duecahulgo’ as a new and distinct Calibrachoaplant:

-   -   1. Compact, semi-upright and outwardly spreading to trailing and        decumbent plant habit.    -   2. Freely branching habit.    -   3. Early and freely flowering habit.    -   4. Large orange-colored flowers with brownish red-colored        centers and venation.    -   5. Good garden performance.

The new Calibrachoa can be compared to plants of the female parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe female parent selection in flower color as plants of the femaleparent selection have apricot-colored flowers.

The new Calibrachoa can be compared to plants of the male parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe male parent selection in flower color as plants of the male parentselection have salmon-colored flowers.

Plants of the new Calibrachoa can also be compared to plants ofCalibrachoa sp. ‘Celebration Corona’, not patented. In side-by-sidecomparisons, plants of the new Calibrachoa differed primarily fromplants of ‘Celebration Corona’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were larger than plants of        ‘Celebration Corona’.    -   2. Plants of the new Calibrachoa were more freely branching, had        shorter internodes and were denser and fuller than plants of        ‘Celebration Corona’.    -   3. Plants of the new Calibrachoa had longer and narrower leaves        than plants of ‘Celebration Corona’.    -   4. Plants of the new Calibrachoa were more freely flowering than        plants of ‘Celebration Corona’.    -   5. Plants of the new Calibrachoa had larger flowers than plants        of ‘Celebration Corona’.    -   6. Plants of the new Calibrachoa and ‘Celebration Corona’        differed in flower color as plants of ‘Celebration Corona’ had        lighter orange-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Calibrachoa plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Calibrachoa plant. The photograph is a sideperspective view of a typical flowering plant of ‘Duecahulgo’ grown in acontainer.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in 10.5-cm containersin a glass-covered greenhouse in Rheinberg, Germany and under culturalpractices typical of commercial Calibrachoa production. During theproduction of the plants, day and night temperatures averaged 18° C. andlight levels averaged 4,500 lux. Rooted young plants were pinched onetime three weeks after planting and were 13 weeks old when thephotograph and description were taken. In the following description,color references are made to The Royal Horticultural Society ColourChart, 2001 Edition, except where general terms of ordinary dictionarysignificance are used.
